Product code: XPA-CB-12034-APO XPander optical detectors are recommended for use as general purpose smoke detectors for early warning of fire in most installations. XPander optical detectors operate on the well established light scatter principle. The optical design of the XPander optical detector allows it to respond to a wide spectrum of fires
Product code: XPA-HT-11170-APO There are two heat detectors in the XPander range, designed to suit a wide variety of operating conditions. A Static Heat Detector (CS) which responds only when a fixed temperature has been reached and a Rate-of-Rise Detector (A1R) which has a fixed upper limit, but in addition, measures the rate of increase in temperature.
Product code: 55000-550APO The XP95A Ionization Detector uses a low activity radioactive foil to detect fires by irradiating the air in the smoke chambers and causing a current fl ow. If smoke enters the chamber, the current fl ow is reduced leading to an alarm.
